Acandy company claims that 12% of its plain candies are orange, and a sample of 200 such candies is randomly selected. a. Find the mean and standard deviation for the number of orange candies in such groups of 200. H = D (Do not round.) a = D (Round to one decimal place as needed.) b. A random sample of 200 candies contains 8 orange candies. Is this result unusual? Does it seem that the claimed rate of 12% is wrong? 0 A. Yes, because 8 is below the minimum usual value. Thus. the claimed rate of 12% is probably wrong. 0 B. Yes, because 8 is within the range of usual values. Thus, the claimed rate of 12% is probably wrong. 0 C. Yes, because 8 is greater than the maximum usual value. Thus, the claimed rate of 12% is probably wrong. 0 D. No, because 8 is within the range of usual values. Thus, the claimed rate of 12% is probably wrong
